Iron stroker?
If I was going that way, I would do a Darton-sleaved block, right? Why is a C5R better than a Darton? Do Darton's have reliability issues too?
4.000 stroker crank is the biggest I would ever go in a motor that is <4.150 bore.
anyway, I can't say where I saw the price on the block/crank combo, but I will say it was through someone on the board...keep looking if you really want some of that stuff.
the stock stroke is 3.622 so 4" is pretty big. and there's a difference between max torque
and a lot of flat usable torque. sure the longer stroke will help...but your choice for cam and heads really tell you the power under the curve. contact Thunder Racing (or just Jason99TA) about a 408" iron block he helped build. it made 510rw and nearly 500ft-lbs with a solid roller. Is the sleeved block you refer to a Darton block? If yes, and I go with a stroker crank, I also will need to incur the cost of clearancing the block, right?
Is this something that can be done without the assistance of a machine shop?
...it does not seem cost effective to use a stroker crank in a stock block to achieve 383CI. it seems to me that if you going to pay for a forged billet crank that you might as well go >400CI???
The Best V8 Stories One Small Block at Time
.I would have never bought my 6.0 block if I knew what I know now.You guys should ask yourself why alot of the guys that had 6.0 blocks in the past have gotten rid of them(PSJ myself many others).Its not because its stronger or better.I it was me I would save a little longer and get the sleeved block.At a later date do the other weight reduction mods as the wallet permits.You wouldnt be handicapped by the extra lbs. Just my 2 pennies Total = $2900
No core charge for a new GM iron block.
Total - $400-$600 (used-new)
If you have a core laying around, than great but I didn't since I'll be selling my stock LS1 complete to help pay for this over-priced engine build. The sleeve blocks are nice but thats still too much for me to spend on a block. If anything, I would of just stayed with the stock bore size (alum) and not go sleeved.
I still think an iron block can handle more boost than alum. (excluding C5R) Aren't the 03 cobra's iron compared to the previous years which are alum?
Supra=iron.
If anyone can PROVE that an iron block is not stronger than a alum block then I'd be more willing to shell the money for the alum. I'd rather have an engine that would live longer on boost than one thats lighter not to mention I'm saving a few bucks so I can still take the wife out for a nice dinner.

So if I go with an ARE aluminum block at $3K, add new pistons and rods, balancing I'm over $4.5K with a stock crank...this does not make economic sence, right?
What is the max CI for a Darton ARE block with a stock crank - 383?
However, it does not say Darton-sleeved blocks....
Anyone know about these?
Considering the number of horror stories about dropped sleeves, I woould be reluctant to go with anything less than a Darton sleeved block. Right?
So thats $2500 with core charge or is the core extra? Where did you see that? I found their block prices here:

anyways, what i really wanted to say is, that if i wanted a sleeved block, i'd go ARE. however they have their sleeves, it wouldn't matter to me because if they are running 8's on the same type block i'd be getting, then i'd have no worries.

Anyway, like I said, I think a big crank is a big waste. People are making 450/450 with a SMALL cam...peaking at like 6100 on a 382cid. Its probably what you want.
Well that is my point I suppose ...with H/C I'm near 420rwhp now...
with the 383, however, i assume the torque under the curve is bigger throughout the hole (no pun) rpm range, right?
..So is all this worth the extra dough?
if this is a straight street car...less rpm is better (imo) and more power under the curve ALWAYS wins. plus, any combo (given the same heads/cam) will make more power with more cubes.

So you would keep the stock crank and go with a sleeved block and new pistons for an all-bore 383?
So the cost is $2,500 for the sleeved block and $600 or so for the pistons...??? I don't need new rods, right?
